Ergonomic ring scanner oriented in a neutral grip position and charging cradle assembly

ABSTRACT

Embodiments position a barcode reader, or other optical detector, to scan upright barcodes when the user hand is in the neutral position. To do this, embodiments rest the body of the ring scanner device on top of the index finger, with the palm facing inward toward the users body. Embodiments have integrated interactivity, including a touchscreen display and separate buttons that can be used to operate the optical detector and input data into an integrated computing device. The integrated computing device can run software applications on board the ring scanner device. Finally, the integrated computing device can be remotely managed.

BACKGROUND Field

This field is generally related to scanning devices.

Related Art

Optical labels, such as barcodes, represent data in a visual,machine-readable format. One type of barcode, known as linear orone-dimensional (1D) barcodes, can represent data by varying the widthsand spacing of parallel lines. Another type of barcode, known as matrixcodes or two-dimensional (2D) barcodes, uses rectangles, dots, hexagonsand other patterns to represent data.

Barcodes have many applications. In stores, universal product code (UPC)barcodes are pre-printed on most items and are used for inventory and tocheck out. Barcodes are used in healthcare and hospital settings, forthings like patient identification (to access patient data, includingmedical history, drug allergies, etc.). They can also be used to keeptrack of objects and people; they are used to keep track of rental cars,airline luggage, nuclear waste, registered mail, express mail andparcels. Barcoded tickets allow the holder to enter sports arenas,cinemas, theatres, fairgrounds, and transportation, and are used torecord the arrival and departure of vehicles from rental facilities etc.

A barcode reader (or barcode scanner) is an optical scanner that canread printed barcodes, decode the data contained in the barcode and sendthe data to a computer. One type of handheld scanner is gripped in auser's palm. With these handheld barcode scanners, the user encloses thehandle with all five fingers and uses the trigger button to activate thescanner, like the operation of a handgun. One downside of the handheldbarcode scanners is that the user of the scanner has to put down thescanner to use his hand. If the user is transporting packages or takinginventory having to repeatedly put down and pick up the scanner canresult in lost productivity.

To reduce this inefficiency, ring scanners operate by looping around atleast one finger, enabling an operator to continue using both handswhile carrying the scanner. In this way, workers can continue to useboth hands when climbing ladders or stairs, handling large items, oroperating machinery. One such ring scanner is illustrated in FIG. 1.

FIG. 1 shows a diagram 100 that illustrates a ring scanner 104 beingheld by hand 102. Ring scanner 104 includes a barcode scanner 106 and abutton 114. Button 114 is positioned to be selected by a thumb 112 ofhand 102. Ring scanner 104 has a loop (not shown) through which an indexfinger and middle finger of hand 102 pass through. With the index fingerand middle finger of hand 102 through the loop of ring scanner 104,barcode scanner 106 rests on top of the index and middle fingers of hand102.

As illustrated in diagram 100, ring scanner 104 is oriented to capture abarcode 106. When thumb 112 selects button 114, barcode scanner 106projects light 108 to read barcode 106. In this example, barcode 106 isa one-dimensional barcode. To capture the barcode 106, hand 102 ispronated, that is, a palms-down position with thumb 112 pointed inwardtoward the body. To orient hand 102 in pronation, the user must twistits forearm 118. Repeated or excessive pronation can lead to fatigue,discomfort, pain and eventually injury.

In addition, prior art ring scanner 104 lacks capabilities beyond theability to scan data. To add additional capabilities such as to outputand input data, a secondary device 110 is strapped to the user's forearm118 and is connected to the ring scanner 104 using a cable 120. However,having a secondary device 110 attached to a user's forearm adds bulk anddiscomfort.

In some cases, ring scanners are not even connected to such secondarydevices. If output is needed for the operator, it may be presented in aseparate screen that the operator might not even be viewing. In oneexample operation, a postage worker may be scanning packages and somesubset of those packages may be flagged for the postage worker to takeaside for further inspection. In the postage worker example, there maybe a separate monitor that displays data when the worker scans a packagethat needs special treatment.

Finally, many ring scanners lack the ability to update their operationremotely. In general, most ring scanners have static operation that ispreprogrammed and hardcoded. To alter operation of the device, anadministrator often has to be in physical contact with the device.

To address these issues, improved rings scanners are needed.

DETAILED DESCRIPTION

As described above, prior art ring scanners typically situate the mainbody of the device, including the optical scanner, to rest on the middleand index finger, opposite of the user's palm. Moreover, these ringscanners normally have the barcode reader oriented to scan uprightbarcodes when the user's hand is pronated. Embodiments disclosed hereinovercome these issues by instead positioning the barcode reader, orother optical detector, to scan upright barcodes when the user hand isin the neutral position. To do this, embodiments rest the body of thering scanner device on top of the index finger, with the palm facinginward toward the users body.

Also, as described above, prior art ring scanners are limited in theirinteractivity. The most part, the ring scanners lack output displaydevices or input devices, and instead rely on external devices, perhapsstrapped to the user's forearm. Embodiments have integratedinteractivity, including a touchscreen display and separate buttons thatcan be used to operate the optical detector and input data into anintegrated computing device. The integrated computing device can runsoftware applications on board the ring scanner device.

The integrated computing device can be remotely managed. A mobile devicemanagement console allows an administrator to control, secure, andenforce policies, and install and uninstall applications on the ringscanner devices. In this way, embodiments provide remote management of awhole group of ring scanner devices. Aspects of each of theseembodiments and advantages, along with other features and advantages,are described below with respect to the accompanying drawings.

FIGS. 2A and 2B are diagrams illustrating a ring scanner in operation,according to an embodiment. FIG. 2A shows a diagram 200 with auser/operator having a hand 204 and forearm 202. Hand 204 is gripping aring scanner device 212. Ring scanner device 212 has a display 208 andan optical detector 210.

As can be seen in diagram 200, ring scanner device 212 has a loop 216through which an index finger 218 and a middle finger 220 pass throughto grip and hold ring scanner device 212. Loop 216 is configured to begripped by index finger 218 and middle finger 220. It presses againstthe palmar side of index finger 218 and middle finger 220. Because loop216 enables an operator to grip ring scanner device 212 with just a looparound the operator's fingers, the operator maintains use of her hands.For example, the operator can continue to use her hands to operateequipment, carry packages, and climb ladders.

According to an embodiment, loop 216 is configured to be gripped byindex finger 218 and middle finger 220 such that the palm is in aneutral position when the optical detector is oriented in an uprightdirection. In this way, a user need not pronate the hand whentransitioning from using the hand to grip a package from the package'sside to scanning the optical label. The user's forearm 202 need nottwist when scanning. Avoiding twisting in this way, embodiments canavoid fatigue, discomfort, pain and even possible injury.

The variousservices provided by device management server 806 may include: (i)ensuring that devices 802A-N are configured to a consistent standard andsupported set of applications, functions, or corporate policies, (ii)updating applications, functions, or policies installed on devices802A-N, (iii) ensuring that users use devices 802A-N in a consistent andsupportable manner, (iv) ensuring that devices 802A-N operate correctly(diagnosing and troubleshooting device 802A-N), and (v) monitoring andtracking devices 802A-N (e.g. location, status, ownership, activity).

Device management server 806 may provide the management services to thedevices 802A-N via a push message over network 804. Device managementserver 806 may send the push message to devices 802A-N, without devices802A-N first requesting that message. The devices 802A-N may execute adevice manager 904 daemon (discussed further below with respect to FIG.9) that listens for the push message to update any changes to themanagement services. Additionally or alternatively, devices 802A-N mayperiodically or intermittently poll device management server 806 for anychanges to the services.

Device management server 806 may be implemented on any computing device,including processor and memory. It may also include a plurality ofcomputing devices, such as a server farm.

In various examples, communication between device management server 806and devices 802A-N may be based on extensible web service capabilitiesusing standard and open protocols, such as XML (Extensible MarkupLanguage), HTTPS (Hypertext Transfer Protocol Secure) to supporttransactions over the secure network connections.

Once a device has enrolled in an enterprise service (i.e. has become amanaged device), according to one embodiment, management services may bedelivered to the managed device from a management server of theenterprise service securely via a mechanism leveraging a push networkcoupling the management server and the mobile device. The push networkmay enable the management server to push a notification to wake up themobile device (or a device manager waiting in the mobile device) forreceiving management services. In turn, after verifying a trust of thenotification pushed, the mobile device may poll the management servervia separate secure network connections to retrieve commands for themanagement services via the secure network connections. The managementserver may be based on extensible web service capabilities usingstandard and open protocols, such as XML (Extensible Markup Language),HTTPS (Hypertext Transfer Protocol Secure) to support transactions overthe secure network connections.

FIG. 9 is a diagram illustrating functional modules of a ring scannerdevice 802 and device management server 806, according to an embodiment.These various functional modules are preferably implemented as softwaremodules, but can be implemented in whole or in part in hardware,firmware, software, or any combination thereof.

As illustrated in FIG. 9, ring scanner 802 includes an application 902,device manager 904, which is coupled to a policy 912, and an operatingsystem 914.

Application 902 is software to carry out a specific task other than onerelating to the operation of the computing device itself, typically tobe used by end-users. Application 902 may specify operations notperformed by system software, relating to the operation of the computer,and utility software (both of which may be provided by operating system914). In an embodiment, application 902 specifies how a ring scanner'sprocessor is to update the ring scanner's display responsive to the datainput from input device.

In one example operation, application 902 may cross-reference the codedecoded from an optical scanner with a list, for example, a list ofknown packages that are to be intercepted. When the code is on the list,it may notify an operator of the ring scanner device. For example, itmay notify the operator by displaying a message on its screen, playingan audible sound, and/or activating a vibration.

Device manager 904 is a process to implement device management serviceson ring scanner 802. To implement device management services, devicemanager 904 may include one or more daemons that listen for instructionsfrom device management server and implement the received instructions.Device manager 904 may also report to device management server 806 anyrequested device configuration information, diagnostic information, ortracking information.

In one embodiment, device manager 904 may be a daemon process whichsleeps while waiting for a notification pushed from management server806. A processing unit may suspend a process or thread in a sleep stateand execute other processes or threads. The processing unit may continueto execute the suspended process or thread when they wake up from thesleep state.

Device manager 904 may wake up in response to the notification received.For example, device manager 904 may initiate secure network connectionsvia network 804 with management server 904 to perform managementoperations. Device manager 904 may go back to sleep, e.g. wheninstructed by the device management server 806 or when deferringperforming certain management operations. In some embodiments, devicemanager 904 may disconnect the secure network connection prior to goingback to sleep.

Device manager 904 includes an application manager 906, security manager908, and location tracker 910.

Application manager 906 is configured to receive, via the networkinterface and from device management server 806, any new or updatedapplication. Application manager 906 can also install the new or updatedapplication to update the operations of the ring scanner device. Thisinstall may, for example, involve requiring a restart of ring scanner802. Additionally or alternatively, application manager 906

Security manager 908 receives from device management server 806 anyupdates to policy 912 and enforces the policy 912. In examples, policy912 may specify security rules restricting user access to ring scanner802 in a manner that promotes security. Such security rules may includedevice lock and passcode/password rules and renewals, user roles, andaccess to application 902.

In addition, security manager 908 may support other security commandsfrom device management server 806. For example, security manager 908 mayexecute a command from device management server 806 to erase ringscanner device 802 (e.g. to completely reconfigure a mobile device twofactory defaults). Security manager 908 may service queries of deviceinformation (e.g. device capacity, serial number etc.), and networkinformation (e.g. phone number, subscriber identity module numbers,media access control addresses), policy 912 and installed applications

Security manager 908 may include an identity certificate as acertificate payload for ring scanner 802 to authenticate itself tomanagement server 101 over SSL network connection via network 804. Oncea management profile is removed (or uninstalled) from device database808, a corresponding ring scanner may no longer be managed by devicemanagement server 806.

Location tracker 910 enables device management server 806 to query ringscanner device 802 for location information. Location information mayinclude network information (such as a Wi-Fi SSID). In an alternativeembodiment, ring scanner 802 may have a GPS receiver and the locationinformation may be coordinates from a satellite-based global positioningsystem. Location tracker 910 may also receive a message from devicemanagement server 806 to ping for a lost device. When location tracker910 receives the ping request, it may play an audible sound to helplocate ring scanner device 802.

Operating system 914 is a system software that manages computerhardware, software resources, and provides common services for computerprograms. An operating system (OS) is system software that managescomputer hardware, software resources, and provides common services forcomputer programs.

Operating system 914 schedules tasks for efficient use of the systemresources (such as processor and memory resources). Operating system 914acts as an intermediary between programs and for memory allocation andaccess to input and output components. For example, as application 902is executed by processor 702, application 902 may make system calls tooperating system 914 to access output devices. Or, application 902 maybe interrupted by operating system 914 in response to an input device.An example of Operating system 914 is the ANDROID operating system,available from Alphabet, Inc. of Mountain View, Calif.

Management console 903 enables an administrator to control devicemanagement server 806. For example, in response to user input intomanagement console 903, device management server 806 can update policy912 or application 902, query the scanner device for locationinformation, and ping the scanner device to emit an audible sound tohelp locate the ring scanner device.
